DTD143ECHZGT116

Overview

The DTD143ECHZGT116 is an NPN digital transistor from ROHM Semiconductor, housed in a surface-mount SOT-23 (SST3) package. It integrates bias resistors with typical values of 4.7 kOhms for both R1 and R2. The device supports a maximum collector current of 500 mA and features a transition frequency of 200 MHz. Key electrical parameters include a DC current gain (hFE) minimum of 47 at 50 mA and 5 V, and a saturation voltage of 300 mV at 2.5 mA base and 50 mA collector currents. It operates within a temperature range of -55°C to +150°C and holds AEC-Q101 automotive qualification.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design by eliminating the need for external input components.
• Automotive-grade reliability certified under AEC-Q101 standards for robust performance in vehicle applications.
• Optimized for high-speed switching with a 200 MHz transition frequency suitable for interface and driver circuits.

Applications

• Inverter circuits
• Interface logic
• Driver circuits

Procurement Notes

Verify component authenticity through authorized channels or official manufacturer documentation. Confirm that the specific suffix matches the required automotive grade and packaging format. Cross-reference datasheet revisions to ensure compatibility with existing designs. Request test reports if required for quality assurance protocols.

Selection Notes

Select this component when an NPN configuration with 500 mA capacity and 4.7 kOhm internal biasing is required. Ensure the application demands AEC-Q101 compliance and operation up to 150°C. Verify that the SOT-23 footprint fits the PCB layout constraints and that the 200 MHz speed meets signal requirements.

Part Context

This part belongs to the DTD143 series of pre-biased NPN transistors. It shares the same basic product number but differs in packaging and tape specifications compared to non-ZGT variants. The ZGT116 suffix indicates the specific reel taping format used for automated assembly processes.

Replacement Considerations

Direct substitutes include DTC143ECAHZGT116 for PNP polarity or DTA143TCAHZG for alternative PNP configurations. Verify pinout compatibility and electrical ratings before substitution. Check for equivalent AEC-Q101 certification if automotive usage is mandatory.
